Idle time for the turbo to cool down
How long do I need to idle before I shut off the engine? In the booklet that came with the truck says to high idle to cool down the turbo but doesn't say how long. I know some you let the truck idle for 15 minutes and others as short as 3. Just over 1500 miles and I've already used half a gallon of oil. Over all, I like this truck.
Is this a good question?
